LUBRICATOR.

Specification of Letters Patent. Pgbpu@ @@pjo 4t, 191'?,

Application led November 17, 1916. l Serial No. 131,809.

To au u1/1.0m t may concern:

Be it known that I, FRANK A. MnoirEL, a citizen of the United States, residing at the city of Lakewood, in the county of Cuyahoga and State of Ohio, have invented a new and usefuli Improvement in- Lubricators, ot'- which the following is a specification, the

' principle of the invention being herein explained and the best, mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

T his invention relates to lubricators and more particularly to a duplex construction adapted for connections with shackles such as are commonly employed in vehiclesprings of the automobile industry.

I have discovered that noises such as squealing and rattling which are communicated during the flexing of automobile springs are traceable to the lateral rubbing 'of the shackles with the springsrather than to the interaction of the leaves. It is therefore desirable to effect a continuous and uniform application of lubricant to the shackle and to accomplish this in a simple, durable and easible manner. 'Besides this need I have had the general object in view to provide a, construction which is sightly in appearance, readily attached lor detached and always certain to exercise its intended purpose.

l rattle,

quently fell oi entirely.

` the practice has Heretofore, so far as I have become aware, been to employ a pair of separate oil cups for conducting the lubricant to the bolt bearings at each shackle. These constantly tended and regularly did loosen so that they not only increased the but functionated unreliably and fre- Moreover it was necess y to fill each separately with attendan loss of time.

Accordingly, a particular object is to pro vide a duplex intercommunicating oiling facility forA each shackle which will eiectV a locking connectiony and prevent the loosening or eventual loss of the reservoirs, and incidentally steady the shackle as a whole and reinforce against lateral vibration at the required movable connections thereof. Another special object is to contrive al structure which is adjustableand capable ofbeing extended or contracted when necessary.

With the foregoing and other objects in view the invention consists of the: novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, whereinis shown an embodiment -gof the invention, but it is to be understood -lthat changes, variations and modifications can be resorted to which come within the sco e of the claims hereunto appended.

dverting to the drawing:

Figure I is a side elevation of a pair of spring ends nio-vably connected and additionally provided with a lubricator embodying my invention. r

Fig. II is a 4section on line II-II of Fig. I looking in the direction indicated by the arrows.

y Fig. III isa perspective view of one detail; and l- IW* is a similar view oi' another dea1 A pair offspring ends 1 and 2 are provided with superposed hollow scrolls 3 and et at their extremities respectively. Inserted through the scrolls 3 and 4 respectively are a pair of spring bolts 5 and 6 adapted to be secured on the opposite sides by castcllated' hangers 9 and 10.- Each of the bolts is provided witlt right angled ducts 11 and 12 respectively, iwlfiich include upward extensions terminatingrin grooves 13 and 14 about midway of the bfaringsurface afforded between the bolts andthe scrolls as is clearly shown in Fig. II. Where the ducts 11 and 12 emerge through the bolt heads they are tapped to somewhat greater size as is seen at 15 and 16. So much` as has been already described is common' to the art.

The lubricator embodying the features of. my invention is a unitary structure adapted to supply the lubricant through both of the ducts l1 and 12 and incidentallyl achieve marked advantages when the shackle connection between the spring ends Vis Jfunctionating. I employ a pair of reservoirs 1f? and 1S having projections 19 and 20 adapted to have pipe thread connections with the lopenings 15 and 1 6 respectively. Intercommunicating outlet ducts 21 and 22 are provided as is also apparent from an inspection of Fig.. II. 4The upper reservoir 17 has 'a `lower screwthreaded opening 23 and the lower reservoir`18-zhas an upper plain opening 24C. The upper reservoir 17 has an upper minate at one endagainst a shoulder 29 of. the upper largenl portion of the tube. Thisllatter is provided in its upper extremity with a pair of slots into which a 'screw driver may be inserted for a plur'pose'to be later explained. The other end of the tube 27 -is ot'. lesser diameter thanthe threads "28 andV is smooth. -As so constructed the tube 27 Vis adapted for insertion through the is slipped over the lower extremity 31 of the- -i inlet 25- while its threads coactwith the y threaded opening23 and its end 31 has a telescopicfit with the opening 24.' In this way the reservoirs 17 and 1.8.are so connected-that lubricating fluid may be supplied to both through the inlet 25'upon removal of the cap 26. A collar 32 is provideda't oneend-with interior screw threads 33 adapted to co-act Vwith the screw threads 28, so that its other end may be caused'to approach or recede from a fiber washer 34 interposed between it and the upper edge of the opening 24. By this meansthefspacing between the reservoir 17A and 18 vmay be adjusted according` to the length of the col# lar 32 and a tight connection maybe had at the upper end of the telescopic connection with the lower reservoir to preclude seepage at that point. It will be noticed vmoreover Vthat the upper larger 'end ofthe .tube 27 extendsfa considerable distance' across the reservoir 17 for the purpose of preventing ervoirs each provided-with an outlet, a duct the gravitational tendency of the -lower reservoir to drain the upper.

In attaching my lubricat'or the reservoir' 18 is firmly seated in the bolt 6 and the reservoir-17 in the bolt 5. Thereafter, the tube 27 is inserted down through the opening 25 and also through the opening 23 until'the threads 28 engage with the threads in such: opening. Before the openings 23 and 24 are brought into line--thecollar 32 tube and then the -whole brought into line. Thereafterthe tube 27 may be turned by a screwv driver until the shoulder 29 im inges against the bottom of the reservoir 1%. In

this manner the height of the top of the tube 27, with reference to 4the interior of the reservoir 17, is established according to predeterminedexpediency. In' the meantime the lower end 31 will have enteredthe opening 24 and'thus eifectually hinder any further rotatory movement onthe part of the reservoirs 17 and 18 relative to the bolts.

Moreover, the tipping of the reservoirs'is thereby. prevented and by reason of the firm anchorageofthe' luhricator, as a whole in` theboltshe shackle is m'easurably'stiii'ened and eliabledlto resistl wrenches and' lateral vibration. It is'."Sappa'reiit4 that the oil in thev upper reservoir 'is trapped below the upper-end of lthe tube,27.so that it may be drained only through the duct l11. I

In order for the tube 27 to reach the limit of its downward movement the threads 33 .on the-collar 32 must'have been first caused to ,engage and moved upwardly along the tube 27. Finally the collar 32 is again screwed downwardly.' until it tightly engages the washer 34'and thus prevents seepage past the connection .at such point. When shock absorbers are employed it may become necessary to allow of *relative movement between the reservoirs 17 and 18 and in such event the collai` 32 may be either entirely dispensed with or made sh'orterthan the normal spacing between the lower edge of the fpengig 23'il11dth'e uppgedge ofthe open- 1n y'invention incidentally'coaets with the 1 felt lining of spring-covers in such a way that oil"which can only seep out, between 'the hanger's'iand'the scrolls, is necessarily conducted-to such felt.
